I wonder if plain vanilla would work? Or FA Vanilla Tahiti?
Sounds like a great recipe!
I feel sure that it would. I have some vanillin that I have been meaning to dissolve and try. At the time, the Vanilla Swirl was all that I had handy.
Something that I forgot to mention is like with all creamy, caramel type vapes, I have found that it is best to steep this for 5 days before deciding if you like it or not.
